This invention relates to stock transfer apparatus or so calledmechanical hot-ibeds off the skewed roller type such as are employed inrollingniills, and has particularrefrence Qto' an" improved drive meansfonthe rollers ofsuch'apgaratus.

The run-out table comprises relatively narrow, elongated structurehavinggoneww more longitudinally extending channels; "10 I e 8 i v atthe bottoms'of which are supporting roll-5- or "other stock; dsigg natedas a, coming from theformingrolls" being adapted toenter said channel orchan f nels and to" rest onithe rollers llwhereby the stock isfsupportedand guided'inits move ment from theforming rolls. Therollers maybedriven in-any'suitable manner to effect movementof the stockalongtheclia'n nel or channels 10. For examplq-i electric m0tors-12 maybe coupld'i'ih dfiying relationtothe individualjrollers 115 i Y f Theshear table '13 'is disposed-"as"aforesaid parallel toandlaterally-spaced'from the'run j out table Aand is'inclusive of "aplurality of v transverse supporting rollers {13 "disposed "at spacedintervals along the length of the table and driven for example .byindividual electric motors 1.47.

The transfer rollers C are disposed hori- 5 zontally, or substantiallyhorizontally, and extend obliquely between the tables A and B, beingjournaled at their ends adjacent to the run-out table A insuitable'bearings 15, and being supported adjacent to their oppositeends on anti-friction rollers 16.

The stock a is adaptedto be lifted from. the channel or channels anddelivered onto the transfer rollers C in any suitable or known manner,and the transfer rollers are adapted tobe driven whereby,

I skewed disposition of said is laterally shifted more or less slowlyfrom the run-outtable to the shear table, the stock thus being permittedto cool before being delivered by the transfer rollers onto the sheartable rollers 13, which latter rollers serve to V carry the stockrapidly away'for stacking or further'treatment.

Referring now for the transfer rollers C; with which the presentinvention is particularly concerned, it will beobserved that eachtransfer roller has fixed to the journaled end thereof a] ratchet wheel17, and that rotatably mounted "on the same end of each roller is alever arm 18 to which is pivoted a pawl 19 cooperating with the ratchetwheel 17 Thus,oscillation of the lever arms 18 obviously is effective toV produce intermittent rotation'of the transfer I rollers in a singledirection.

, Mounted in an axial bore in each leverarm 18 for rotation and forlongitudinal sliding movementtherein is a shaft 20 which is bifur-,

cated at itsouter end to receive a block=21,

said block being mounted on said shaft by a pin or studs 22 extendingthrough the ears 23 7 formed by the bifurcation, whereby the block isrotatable on an axis disposed at right angles to the axis of the shaft20. The several blocks I 21 are connected together by arod or rods 24:

to which the blocks are'pivotally connected by pins or studs 25 disposedwith their. axes in the same plane but at right angles to the axes ofthe pins or studs 22. Thus, universal V Y between the rod or rods24 andthe respective lever arms jointv connections are provided 18, and as aconsequence reciprocationof the rod or rods 24 obviously iseffective topro duce oscillation ofsaid lever arms with red *sultant intermittentrotation'of the transfer rollers, the rod or rods 24: simply shiftinglaterally during reciprocation thereof due to the axes of the transferrollers being disposed diagonally to said rods. 7 By reason of theforegoing arrangement it is obviously immaterial to the efficientcollective rotation of the transferrollersfwhether any particular'rolleror its bearing has deviated for any reason from its original pos tion.Consequently, the troubles heretofore due to the oblique 'or rollers,the stock to the driving mechanism experienced in the driving of skewedtransfer c designated generally .as'30 with the rods 24,

said shaftbeing oscillated by means of a suitable motor M-theshaft 31 ofwhich carries a crank 32 connected by a link 38 with a crank 34 on theshaft 26;

, In order topermit the necessary lateral movement of the rods 24, theshaft 26 preferably is disposedparallel to the transfer rollers, and the'universaljoint 30 preferably is of the same construction as theuniversal joint connections between the the lever arms 18. However,other means rods 24 and may be provided for reciprocating the rods i,

, 1. In a drive'mechanism" for skewed 011} ers, a reciprocal drivingmember, a roller dis posed obliquely with respect to the direction saiddriving member, and r a connection between said driving member ofreciprocation of the appended claims.

and said roller whereby reciprocation of the a former rotates thelatter.

" 2. In a drive mechanism for skewed'rollers, a reciprocal drivingmember, a roller disposed obliquely with respect to the directionofreciprocation of said driving member, and

a connection between'said' driving member and said roller wherebyreciprocation of the former rotates the latter intermittently in asingle direction.

3. In a drive mechanism for skewed rollers,'a reciprocal driving member,a roller disposed obliquely with respect to the direction ofreciprocation of said driving, member, a

lever, a pawl andratchet" connection between said lever and saidroller','and a universal ioint connection between said lever and saiddriving member.

4. In a drive mechanism for skewed roll ers, a reciprocal drivingmember, a roller disposed obliquelyc with respectto the direction ofreciprocation of said driving member, a lever, apawl and ratchetconnection'be tween saidlever and said roller, and a uni VGISalJOlIItconnection between said lever and said driving member, said universaljoint connection being inclusive of a shaft mounted in the lever formovement axially of the lever.

5. In a drive mechanism for skewed rollers, a driving member, aplurality of rollers disposed obliquely with respect to the direction ofreciprocation of said driving member, and a connection between saiddriving memher and each of said rollerswhereby reciprocation of thedriving member efi'ects collective rotation of the rollers.

6.

In a drive mechanism for skewed rollers, areciprocal driving member, a roller disposed obliquely with respect tothe direction of reciprocation of said driving member, a ratchet wheelfixed to the roller, a lever arm pivoted on the roller, a pawl carriedby the lever arm for cooperation with said ratchet wheel, a shaftmounted in the lever arm for rotation and longitudinal movement relativethereto, a member pivoted to said shaft on an axis at right angles tothe axis of the shaft, and a pivoted connection between said lastmentioned member and said driving member on an axis at right angles tothe axis of the pivotal connection of said member with said shaft.

8. In a drive mechanism for skewed rollers, a reciprocal driving member,a roller disposed obliquely with respect to the direction ofreciprocation of said driving member, a connection between said drivingmember and said roller whereby reciprocation of the former rotates thelatter, and means for reciprocating said reciprocal driving member,

said means comprising a shaft disposed par- 7 allel to the roller, meansfor oscillating said shaft, a crank arm on said shaft, and a universaljoint connection between said crank arm and said reciprocal member.
